VEHICLE DOOR OPENING AND CLOSING DEVICE.

Application filed May 29, 1925. Serial No. 33,747.

This invention relates to vehicle door the grip may be grasped by a passenger opening and closing devices and hasfor an and the lever moved to the left in Figure object to provide an improved construction 1 whereupon'the bolt or catch 6 will be reparticularly adapted for taxi cabs or other leased and the door may be opened. The automobiles wherein means are provided lever 9 is pivotally mounted at 11 on the door which will permit the driver to readily 4 and also extends down to near the lower open and close either door without moving end of the door. An L-shaped member 12 from his seat; is rigidly connected to the lower end of Another object of the invention isto prolever 9, said member 12 having the depend- 10 vide a door opening and closing device ing pin or section 13 projecting into the wherein means are provided capable of opline of movement of the shoulder 14 of a eration by the passenger or operation by the reciprocating bar 15. The bar 15 at the driver from his seat, the structure being end opposite the shoulder 14 is formed with such that it may be readily used on autoteeth 16 whereby a rack structure is pre- 7 15 mobiles or any other desired form of vesented designed to be continually in mesh hide with the gear 17. The gear 17 is rigidly A further object of the invention, more secured to a shaft 18 supported in suitable specifically, is to provide a door opening brackets 19 and carrying a comparatively and closing device wherein means are prosmall bevel pinion 20 at the end opposite 7 2o vided for first unlocking the door and then the gear 17. The pinion 20 continually swinging the same to an open position, the meshes with a segmental bevel gear 21 which structure being such that upon swinging the is pivotally mounted on a pin 22 and which door to a closed position the door will autois rigidly secured to a crank 23.
